_ Hoping to learn how to control crop damage by a certain species of beetle, a researcher plans to test two different pesticides in small plots of com. A few days after application of the chemicals, the researcher will check the number of beetle larvae found on each plant. The researcher wants to know whether either pesticide works and whether there is a signicant difference in effectiveness between them. Design an appropriate experiment. O D. Presence of beetle larvae Apply each treatment to the same number of plots of land. To control the experiment, the plots should be as similar as possible; otherwise, use blocking to group plots with similar characteristics. After a given period of time, measure the response variable and compare the results. What characteristics could be used for blocking? Select all that apply. E A. Sunlight [E] B. Type of pesticide used I] C. Size of eld I] D. Proximity to other plants E] E. Presence of beetle larvae [E] F. Water l
